NASA Researchers Studying Advanced Nuclear Rocket Technologies

January 9, 2013

By using an innovative test facility at NASA’s Marshall Space Flight Center in Huntsville, Ala., researchers are able to use non-nuclear materials to simulate nuclear thermal rocket fuels - ones capable of propelling bold new exploration missions to the Red Planet and beyond. The Nuclear Cryogenic Propulsion Stage team is tackling a three-year project to demonstrate the viability of nuclear propulsion system technologies. A nuclear rocket engine uses a nuclear reactor to heat hydrogen to very high temperatures, which expands through a nozzle to generate thrust. Nuclear rocket engines generate higher thrust and are more than twice as efficient as conventional chemical rocket engines.

The team recently used Marshall’s Nuclear Thermal Rocket Element Environmental Simulator, or NTREES, to perform realistic, non-nuclear testing of various materials for nuclear thermal rocket fuel elements. In an actual reactor, the fuel elements would contain uranium, but no radioactive materials are used during the NTREES tests. Among the fuel options are a graphite composite and a “cermet” composite - a blend of ceramics and metals. Both materials were investigated in previous NASA and U.S. Department of Energy research efforts.

Nuclear-powered rocket concepts are not new; the United States conducted studies and significant ground testing from 1955 to 1973 to determine the viability of nuclear propulsion systems, but ceased testing when plans for a crewed Mars mission were deferred.

The NTREES facility is designed to test fuel elements and materials in hot flowing hydrogen, reaching pressures up to 1,000 pounds per square inch and temperatures of nearly 5,000 degrees Fahrenheit - conditions that simulate space-based nuclear propulsion systems to provide baseline data critical to the research team.

“This is vital testing, helping us reduce risks and costs associated with advanced propulsion technologies and ensuring excellent performance and results as we progress toward further system development and testing,” said Mike Houts, project manager for nuclear systems at Marshall.

A first-generation nuclear cryogenic propulsion system could propel human explorers to Mars more efficiently than conventional spacecraft, reducing crews’ exposure to harmful space radiation and other effects of long-term space missions. It could also transport heavy cargo and science payloads. Further development and use of a first-generation nuclear system could also provide the foundation for developing extremely advanced propulsion technologies and systems in the future - ones that could take human crews even farther into the solar system.

Building on previous, successful research and using the NTREES facility, NASA can safely and thoroughly test simulated nuclear fuel elements of various sizes, providing important test data to support the design of a future Nuclear Cryogenic Propulsion Stage. A nuclear cryogenic upper stage - its liquid- hydrogen propellant chilled to super-cold temperatures for launch - would be designed to be safe during all mission phases and would not be started until the spacecraft had reached a safe orbit and was ready to begin its journey to a distant destination. Prior to startup in a safe orbit, the nuclear system would be cold, with no fission products generated from nuclear operations, and with radiation below significant levels.

“The information we gain using this test facility will permit engineers to design rugged, efficient fuel elements and nuclear propulsion systems,” said NASA researcher Bill Emrich, who manages the NTREES facility at Marshall. “It’s our hope that it will enable us to develop a reliable, cost-effective nuclear rocket engine in the not-too-distant future."

The Nuclear Cryogenic Propulsion Stage project is part of the Advanced Exploration Systems program, which is managed by NASA’s Human Exploration and Operations Mission Directorate and includes participation by the U.S. Department of Energy. The program, which focuses on crew safety and mission operations in deep space, seeks to pioneer new approaches for rapidly developing prototype systems, demonstrating key capabilities and validating operational concepts for future vehicle development and human missions beyond Earth orbit.

Marshall researchers are partnering on the project with NASA’s Glenn Research Center in Cleveland, Ohio; NASA’s Johnson Space Center in Houston; Idaho National Laboratory in Idaho Falls; Los Alamos National Laboratory in Los Alamos, N.M.; and Oak Ridge National Laboratory in Oak Ridge, Tenn.

The Marshall Center leads development of the Space Launch System for NASA. The Science & Technology Office at Marshall strives to apply advanced concepts and capabilities to the research, development and management of a broad spectrum of NASA programs, projects and activities that fall at the very intersection of science and exploration, where every discovery and achievement furthers scientific knowledge and understanding, and supports the agency’s ambitious mission to expand humanity’s reach across the solar system. The NTREES test facility is just one of numerous cutting-edge space propulsion and science research facilities housed in the state-of- the-art Propulsion Research & Development Laboratory at Marshall, contributing to development of the Space Launch System and a variety of other NASA programs and missions.

Caçada por submarino evoca tempos da Guerra Fria para Suécia e Rússia

Suecos lançaram operação para localizar embarcação invasora em suas águas; russos negam envolvimento no caso e apontam para a Holanda

Um submarino estrangeiro detectado no arquipélago de Estocolmo provocou a maior mobilização militar na Suécia desde a Guerra Fria, envolvendo o deslocamento emergencial de soldados, embarcações e helicópteros. Nesta segunda-feira, uma zona fechada para voos foi declarada na área de buscas.

Os primeiros alertas começaram a soar na sexta-feira e a suspeita logo recaiu sobre a Rússia, que negou envolvimento no caso e ainda apontou para a Holanda. “É um submarino de propulsão diesel-elétrica holandês Bruinvis que, na semana passada, realizava exercícios bem perto de Estocolmo”, afirmou uma fonte do Ministério da Defesa russo.

Só que o porta-voz do ministério holandês da Defesa, Marnoes Visser, também negou sua participação. “O submarino holandês não está envolvido e nós não estamos envolvidos nas operações de busca lançadas pelas forças suecas”, declarou. “Participamos em manobras com a Suécia e outros navios, mas elas terminaram na terça-feira da semana passada”.

Nas últimas semanas, a Suécia vem apontando uma série de invasões ao seu espaço aéreo por parte de aviões russos, esfriando as relações entre os dois países. Sobre o submarino, especificamente, as autoridades suecas limitaram-se a afirmar que receberam um alerta sobre “atividade submarina estrangeira” no litoral. O primeiro-ministro Stefan Löfven disse que, por enquanto, as missões lançadas pela Marinha são apenas para “coletar informações”.

Segundo uma reportagem do jornal Svenska Dagbladet publicada no fim de semana, o serviço secreto sueco interceptou frequências de rádio em uma área entre o litoral de Estocolmo e o enclave russo de Kaliningrado, onde está localizada grande parte da frota russa no Mar Báltico.

situação expõe a preocupação crescente sobre as intenções de Vladimir Putin na região. Em pouco mais de um mês, surgiram informações sobre um agente de inteligência da Estônia que teria sido levado por forças russas, a Finlândia reclamou da interferência de Moscou em um de seus navios de pesquisa e a Suécia fez um protesto formal sobre uma “grave violação” quando caças russos entraram em seu espaço aéreo.

“Isso pode se tornar um divisor de águas para a segurança em toda a região do Mar Báltico”, escreveu o chanceler letão, Edgars Rinkevics, em sua conta em uma rede social. Autoridades da Letônia apontaram um aumento na presença de submarinos e navios russos perto de suas águas territoriais.

Histórico - Não é a primeira vez que um submarino provoca um estranhamento nas relações entre a Rússia e a Suécia. A caçada desta semana ao submarino misterioso evoca as rotineiras invasões das águas territoriais suecas por embarcações soviéticas durante os anos da Guerra Fria.

No incidente mais notável, ocorrido em outubro de 1981, um submarino a diesel soviético acabou encalhando acidentalmente em uma praia sueca próxima de Karlskrona, onde está localizada a maior base naval da Suécia. No momento mais tenso do episódio, navios de guerra soviéticos tentaram forçar passagem entre a marinha sueca para resgatar o submarino. No final, os esforços de intimidação não funcionaram e os soviéticos retrocederam. O episódio só acabou depois de dez dias de tensão, quando rebocadores suecos acabaram levando o submarino para águas internacionais, onde ele foi entregue aos soviéticos.

Houve também alarmes falsos, ocasiões em que a Suécia pensou ter detectado submarinos quando, na verdade, os sinais haviam sido emitidos por lontras.

Algo de podre nisso?   Girafa sacrificada e esquartejada vira problema para zoológico da Dinamarca.   Há países onde assaltantes queimam vítimas vivas ou tribos rivais se esquartejam mutuamente. Na Dinamarca, a crise do momento foi causada por uma girafa. Jovem demais para se tornar reprodutor e geneticamente muito próximo de outros espécimes, Marius foi sacrificado no zoológico de Copenhague e fatiado em pedaços, alguns enviados aos leões como refeição especial. Tudo na frente de um público composto de adultos e crianças, como uma aula ao vivo do mundo animal. Um abaixo-assinado endossado por 27000 pessoas e reações furiosas não abalaram a direção do zoológico. Ofendidos em seus brios nacionais, especialistas dinamarqueses criticaram a falta de espírito científico dos queixosos e a “disneyficação” dos animais. “Os leões nos zoológicos comem o quê? Couve-de-bruxelas”, perguntou um. [...]   (Veja, 19 de fevereiro de 2014)

Os dias lindos   (Carlos Drummond de Andrade)   [...]   Acontece em abril nessa curva do mês que descamba para a segunda metade. Os boletins meteorológicos não se lembraram de anunciá-lo em linguagem especial. Nenhuma autoridade, munida de organismo publicitário, tirou partido do acontecimento. Discretos, silenciosos, chegaram os dias lindos.   E aboliram, sem providências drásticas, o estatuto do calor. A temperatura ficou amena, conduzindo à revisão do vestuário. Protege-se um tudo-nada o corpo, que vivia por aí exposto e suado, bufando contra os excessos da natureza. Sob esse mínimo de agasalho, a pele contente recebe a visita dos dias lindos.   A cor. Redescobrimos o azul-correto, o azul azul, que há meses se despedaçara em manchas cinzentas no branco sujo do espaço. O azul reconstituiu-se na luz filtrada, decantada, que lava também os matizes empobrecidos das coisas naturais e das fábricas. A cor é mais cor, na pureza deste ar que ousa desafiar os vapores, emanações e fuligens da era tecnológica. E o raio de sol benevolente, pousando no objeto, tem alguma coisa de carícia.   O ar. Ficou mais leve, ou nós é que nos tornamos menos pesadões, movendo-nos com desembaraço, quando, antes, andar era uma tarefa dividida entre o sacrifício e o tédio? Tornou-se quase voluptuoso andar pelo gosto de andar, captando os sinais inconfundíveis da presença de dias lindos.   Foi certamente num dia como este que Cecília Meireles escreveu: “A doçura maior da vida flui na luz do sol, quando se está em silêncio. Até os urubus são belos, no largo círculo dos dias sossegados.” Porque a primeira consequência da combinação de azul e leveza de ar é o sossego que baixa sobre nosso estoque de problemas. Eles não deixam de existir. Mas fica mais fácil carregá-los.

Em “Discretos, silenciosos, chegaram os dias lindos.“, ocorrem três adjetivos. Sobre a função sintática que exercem, respectivamente, é correto afirmar que:
